Install dual hard disk, how to solve the ATA mode is crucial. If two hard disks support ATA100/133, the proposed dual-IDE hard disk directly connected to an IDE channel, and then drives to install on another IDE channel. If the hard disk and can only support ATA33, then connect the drive can easily lead to lower data transmission speeds, this time performance will be significantly decreased. And if one of the old hard drive can only support ATA66/33, it is recommended it with the drive installed in a channel, then the new large-capacity hard drive on another IDE channel alone. In fact, one IDE channel, install a different ATA-mode device are not to, but it tends to bring about some unexpected failures.
In addition, install a new hard disk, strongly suggest that you re-install the disk drive. After the installation is complete, you can at the hardware Device Manager property of the disk controller, hard drive to see the current working model, in which DMA5 on behalf of ATA100. For non-Intel chipset and Maxtor hard drives supported ATA133, generally do not care too much, because ATA100 for the current internal transfer rate of IDE hard drives have already been more than enough, even ATA133 hard drive work in the ATA100 mode, the performance loss will not be significant. And if the upgrade high-capacity hard drives are SATA interface, so do not worry the identified transmission mode. The IDE drive and SATA hard disk will not affect each other.
